The paper explores Federated Reinforcement Learning (FRL) in the context of actor-critic (AC) algorithms. Specifically, it focuses on Single-loop Federated Actor Critic (SFAC), a two-level federated AC algorithm that enables multiple agents to collaborate and learn a shared policy adaptable across heterogeneous environments. The research provides theoretical bounds on the convergence error of SFAC, showing that it asymptotically converges to a near-stationary point with an extent proportional to environment heterogeneity. Numerical experiments using common RL benchmarks demonstrate the effectiveness of SFAC.

Federated reinforcement learning is a new way for computers to learn together and make decisions. The paper looks at how actor-critic algorithms, which are good at solving problems, can work together in different environments. They created a new algorithm called Single-loop Federated Actor Critic that lets agents work together and share their knowledge. The researchers showed that this algorithm works well and gets better as more agents join in.
